LUBRICATIJNG DEVICE.

Application filed June 14,1921. Serial No. 477,393.

To all whom it may concern:

Be it known that I, CHARLES T. BRADSHAW, a citizen of the United States, residing at West Collingswood, in the county of Cam-. den and State of New Jersey, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification. a

The object of my invention is to provide a lubricating device, for car wheel flanges, of novel, simple and efficient construction which may be readily thrown into an operative position, when desired, to supply a lubricant to the wheel flanges for thelubrication thereof and the track-which they travel at curves, switches and other places where the lubrication isdesired; and with this and related objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter described and' claimed. r

In the accompanying drawings illustrating my invention,

Figure 2 is a view of the device and parts of a car as seen from one end of the car. f

Figure 3 is a sectional detail of one of the pivoted members of the lubricating device and adjuncts. V

Figure 5 is a sectional detail of the oil guard and adjuncts, on line 55 of Fig. 3.

V Figure 6 is a sectional detail of the pivoted member, on line 6-6 ofFig. 3.

Figure7 is a sectional detail of the two way air valve, on line 7-7 of Fig. 2.

Figure 8 is a top view o f'the handle for operating the air valve. 'Figure 9 is a sectional detail of the oil guard and adjuncts, on line 99 of Fig. 3.

Referring to the drawings, 2 designates a portion of the car body, 3 a portion of one of the trucks carrying! the body 2, and- 4 the forward pair of flanged wheels j ournal'ed in the truck 3. The truck 3 includes th'eusual cross bar 6 in advance of the forward wheels, and the construction and operation of the 7 parts thus far described are common and well known and no detailed description or illustration thereof is deemed necessary herein.

Secured to the cross bar 6 adjacent to each wheel 4 1s a bracket7 having two spaced bearings 8 for the reception of the trunnions 9 of a member 10' which is arranged between the bearings 8 and pivotally supported by the bracket 7. The trunnions 9 are formed by a hollow shaftset in the member 10 and projecting from the respective sides thereof.

The member 10 comprises an arm 11 which extends downwardly from the trunnions 9 and an arm 12 which extends upwardly from the trunnions 9 and toward the wheel 4:.

The lower end portion of the arm 11 carries an oil-containihglvessel or box 13, and

the upper end portion of the arm. 12 carries a hollow guard 14 adapted to embrace the flange 15 of'the wheel 4.

The arm is of channel formation and carries an 011 pipe 16v and an air pipe'17 seated therein and suitably securedthereto,

The upper end of the air pipe 17 opens into the guard 14, and the upper end of the oil pipe 16' communicates with" the air pipe 17 below the top thereof. The lower portion of the oilpipe 16 extends do'wn'into the oil box 13 and communicates therewith near the'bottom thereof and the open lower end of the pipe 16 is guarded by a screen 18 to prevent dirt and foreign matter from passing with the oil from the box 13 into the pipe 16.

When compressed air is supplied tothe lower-portion of the pipe 17 and discharged During the travel of the wheel 4, its flange 15 entersand leaves the hollow guard 14 through openings in the end walls'thereof,

and the interior of'the guard 14 is provided with'suitable'baffle walls or wings 19 spaced from its end walls 20 to prevent the oil spray from leaving'the guard through its end openings. e c

The lower end of the air pipe 17 is connected by a suitable coupling 21 to a flexible pipe 22'which is connected to an air passage 23 formed in the body of the bracket 7 and leading to the 1 top of a horizontallyarranged, cylindrical opening v24 in the bracket 7. Slidably fitted within the open- 'iah ing 24e is a cylindrical valve body 2 one-end of which projects from the bracket? toward the arm 11 and the other end of which faces the p en .e an. a r. pi e. screwed into' the wall of the bracket 7' closing one end of the opening 24. WVhen theyalve 25 is in the position shown in Fig; 3, communicat-ion between the air pipes 22 and 26 ;is

established through the opening 24, and, when the-valve 25 is movecLpast the, passage 23 toward the pipe 26,1re ominuni'cation betweenthe pipes 22jand 2 6, is closed, for purposes 5 hereinafter explained;

The tops of the bearings 8 are made open, as shown in the drawings, to permit the easy removal of the trunnions 9 of the members 1O therefrom after uncoupling the flexible pipe 22, so that if one of the members 10 or any of the parts carried thereby becomes broken or fails to operate properly, the member 10 and the parts which it carries may be readily lifted from the bearings 8 and another substituted for it, so that it will not be necessary to keep the car out of service during the repair or adjustment of the defective lubricating part.
